Even if the single-track railway, Railway Turnout the laying of railway turnout, build a section of the length of the cable than the cable, you can off the train. Due to the large number of railway turnout, complex structure, short service life, limited train speed, low driving safety, large maintenance and maintenance characteristics, and curves, joints and called the track of the three weak links. It has three basic forms: the line connection, cross, connection and cross the combination. Commonly used lines are connected with various types of single-type railway turnout and duplex railway turnout; Railway Turnout crossed with straight cross and diamond-shaped cross; connection and cross combination of crossroads and crossroads.
